1 Claim. (01.

The present invention relates to new and useful improvements in smokingpipes and has for its primary object to provide a filter positioned inthe pipe stem and embodies a baffle member having sinuous passagestherein along which the smoke is adapted to travel whereby to increasethe length of travel of the smoke to aid in the dissipation of the heatwith less possibility of particles of tobacco getting through the pipe.

A further important object of the invention is to provide a bafilemember preferably constructed of pressed paper which may be discarded,when desired, and which may act as an absorbent and which also may betreated to release a pleasant odor during the smoking of the pipe.

A further object is to provide a filter of this character of simple andpractical construction, which is efficient and reliable in performance,relatively inexpensive to manufacture and otherwise well adapted for thepurposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout and in which:

Figure 1 is a side elevational view of a smoke pipe constructed inaccordance with the present invention.

Figure 2 is a fragmentary longitudinal sectional view through a portionof the stem.

Figures 3, 4 and are transverse sectional views taken respectively onthe lines 3-3, 4-4 and 55 of Figure 2.

Figure 6 is a perspective view of one of the cork gaskets at the end ofthe filter.

Figure '7 is a side elevational view of a modified lbaffie member.

Figure 8 is a transverse sectional view taken substantially on a line8-8 of Figure 7.

Figure 9 is an end elevational view of the bafile shown in Figure 7.

Figure 10 is a side elevational view of a further modified baflieconstruction.

Figure 11 is an end elevational view of one end of the lbaiile shown inFigure 10.

' end adjacent the disk 22 is formed with an open- Figure 12 is asimilar view of the intake end of the baflle.

Figure 13 is a side elevational view of a further baffle member.

Figures 14 and 15 are end elevational views of the discharge and intakeends, respectively, of the baflle illustrated in Figure 13.

Referring now to the drawings in detail and with particular reference tothe form of the invention illustrated in Figures 1 to 5, inclusive, thenumeral 5 designates the bowl of .a smoking pipe, while the numeral 6designates the bit end and the numeral 1 designates an intermediateconnecting tube therefor. The stem portion of the bowl 5 is reduced asshown at 8 and the inner end of the 'bit 6 is reduced as shown ,ati9 andthe reduced portions 8 and 9 are formed with annular grooves l0 and II,respectively, within which are seated cork gaskets l2 and I3,respectively, the gaskets being split longitudinally as shown in Figure6 of the drawings to permit mounting of the gaskets in position.

The smoke passage in the stem portion of the bowl is designated at M andthe smoke passage in the bit 6 is designated at l5.

Positioned in the tube 1 is a baflle member designated generally at [6and which constitutes a tubular core I! from which longitudinallyextending fins l8 project in a radial direction, the edges of the finsbearing against the inner surface of the tube 1.

I The fins I8 define smoke passages or channels l9 extendinglongitudinally of the baffle, and the opposite end of each alternate ribis notched or interrupted as shown at 20 to provide communicationbetween adjacent passages 19. The ends of the passages I9 adjacent thebit 6 are closed by a disk member 2| and the ends of the passages l9adjacent the bowl 5 are closed by a disk 22, said last-named disk havinga notch 23 formed in one edge thereof to provide communication with oneof the passages l9.

Also positioned in the tube 1 against the disk 22 is a disk 24 ofabsorbent material also provided with a notch 25 registering with thenotch 23. The disk 24 is spaced from the adjacent end of the bowlportion of the pipe shown toadvantage in Figure 2 of the drawings. Thecore ll, at its ing 26, the opening being arranged in the passage thatis remotely connected to the passage communicating with the notches 23and 25 so that the smoke will travel longitudinally through therespective passages in a counter-clockwise order as indicated by thearrow in Figure 4 of the drawings.

In Figures 7 to 9, inclusive, of the drawings, I have illustrated amodified form of bafile designated generally at 21 and in which a pairof the longitudinal ribs 28, at the lower portion of the baffle havenotches 29 formed therein and positioned between said ribs and disposedin the passage therebetween is an absorbent pad 38,

the pad being adapted to absorb any moisture that might be conveyedthrough the baffle together with the smoke. Each alternate rib I 8a atthe upper portion of the bafile has an opposite end spaced from anadjacent disk Zla to provide lateral passages 20:; communicating withadjacent longitudinal passages l9a between the ribs.

In Figures 10 to 12, inclusive, a further modi fied baffie constructionis illustrated and comprises the tubular core 3| around which ispositioned spaced spirally formed ribs 32 and 33.

The core 3| is provided with disks 34 and 35 at its opposite ends, thedisk 34 having an intake T notch 35 therein communicating with thechannel between the spiral ribs 32 and 33 and the return channel,terminates in an opening 36 ,com-

municating with the core. The smoke travels in the manner illustrated bythe arrows in Figure 1d travel in the manner as shown by the arrows inFigure 13 of the drawings.,

From the foregoing it will be apparent that the baffles illustrated inthe several forms of the invention cause the smoke to travel along asinuous path longitudinally back and forth of the baffle and by so doingthe heat is dissipated and the moisture carried with the smoke impingeson the walls of the passages in the baflle and is absorbed thereby.

It is believed the details of construction, advantages and manner of useof the device will be readily understood from the foregoing withoutfurther detailed explanation.

Having described the invention, what is claimed as new is:

A filter for a smoking pipe adapted for mount- -'ing in a pipe stem,said filter comprising a tubudisks at each end of the core sealing thestem,

said core being open at one end and closed at its other end, one of saiddisks having an opening,

and circumferentially spaced longitudinally ex: tending ribs carried bythe core forming a tortuous passage, a pair of said ribs having notcheson the edges thereof andvan absorbent pad positioned between said pairof ribs, said core also having an openin" for receiving smoke from thepassage.
